How were the actual effects of the obesity injections?

I've been hearing a lot about weight loss injections from people around me lately, so I'm looking into it myself. Since I'm not losing weight as much as I'd hoped with diet and exercise alone, I'm curious about the actual effectiveness of these injections. In particular, I'm wondering if appetite decreases significantly when you first start, and how long it takes to see changes in weight.

It seems there are various types of weight loss injections, and the prices and administration intervals also vary slightly. When I search online, I find many posts that feel like advertisements, so I would like to hear from people who have actually received them.

I am curious if the effects of weight loss injections vary significantly from person to person, and I would also like to know if weight returned after stopping the treatment.

If anyone has personally tried weight loss injections, please share an honest review about the product, its effectiveness, and the cost.
